About us

We give full meaning to the word partner.


Prioritising the human

In creating Prime Partners, our intention has been to prioritise the human dimension.

Thanks to a lean, flexible structure, our teams can really give their best. Each of our clients is in direct contact with a partner who provides long-term personalised support.

Because before investing, we always start by listening to you.

To understand your needs, your hopes and your constraints. This is why we favour a relational rather than a transactional approach.

Asset management is a matter of trust. We avoid any conflict of interest and only provide you with personalised solutions.

And because your interests are our sole concern, we carry out our work in accordance with the strictest ethical standards.

Finally, this ethical concern is reflected in our profound sense of corporate social responsibility.


The independent asset manager model.


Solid values, which form the backbone of all our work.

A privileged relationship

Having a single point of contact allows us to build closer relationships. This is the guarantee of successful collaboration.

Long-term partnership

Because you measure time in generations, it is essential to be able to count on your partner over the long term.

Total independence

Thanks to our complete freedom of choice, we offer you optimal solutions at the best possible price.

Absolute impartiality

Free from any conflict of interest, our investment choices and recommendations are always completely objective.

Mutual trust

Without trust, nothing solid can be built. But trust cannot be decreed, it must be earned. It falls to us to do so.

Prime Partners
in a few figures

100% independent, since the very beginning.

From day one, we have always aimed for selective growth, aware that in order to go far we needed to advance one step at a time. Today, we are proud of the progress we have made because we believe that our success is first and foremost yours.
